Rock magnetic properties across several K-T boundary sections have been investigated to reveal any possible magnetic signature associated with the remains of the impact event at the end of the Cretaceous. Studied sections' ...

A new crystalline polymorphic phase of tetrakis(mu(2)-benzoato-O,O')-bis(dimethyl sulfoxide)dicopper(II) was obtained by direct synthesis, in space group P2(1)/n. The copper coordination is in a slightly distorted square ...

Mossbauer spectroscopy, coercive field and permeability were used to study the transformations produced by annealing at 375 degrees C as-quenched amorphous ribbons of Metglas(R) 2605 SC of nominal composition Fe81B13.5Si3.5C2. ...

The linear steady convection of a fluid layer between rigid thermally and electrically non-conducting walls is investigated from three different stand-points: 1) convection of a rotating fluid, 2) magnetoconvection and 3) ...

Using the approach of extended irreversible thermodynamics, we calculated the equilibrium autocorrelation functions for the concentration, the transverse velocity and the viscosity, for a neutral binary mixture of two ...

Palaeomagnetic results for 178 oriented samples from five sections (combined thickness of 75 M) of the red bed Tecomazuchil Formation, southern Mexico are reported. The formation has been assigned to the Bathonian(?)-Callovian, ...

Magnolia guerrerensis from the cloud forest in the state of Guerrero, Mexico, is illustrated and proposed as a new species. This taxon is similar to M. schiedeana Schltdl., but differs from it because of its smaller stipules, ...

Magnolia krusei (Magnoliaceae), a new species from the state of Guerrero, Mexico, is illustrated and described. It is related to M. illisiana A. Vazquez and M. tamaulipana A. Vazquez, but differs from these by its smaller ...

Magnolia vazquezii Cruz Duran & K. Vega (Magnoliaceae) is described as a new species from the state of Guerrero, Mexico. It has been collected only in cloud forest in the state of Guerrero and appears similar to M. schiedeana ...
